Login Form for Windows Application

You're probably not going to find one one simple example that has exactly what you are looking for. I think your best option is to just start making your own example and come back with specific questions when you run into trouble.

This article[^] looks like a good overview about storing passwords. I thought it might help get you started.

Here is a tip/trick[^] that might help, too.

Here's what I would do...

Login Form:

Create a form "frmLogIn", and give is a public property (bool) of IsAuthorized.
Add two text boxes to the form, make one of them a password box (using masking characters).
Add a cancel button (make it the cancel for the dialog), and an OK button (make it the OK for the dialog).
On Cancel, set IsAuthorized to false and close the form (returning control to main()).
On OK, do database verification and set IsAuthorized appropriately (depending on db verification).

Main:

When the program starts, launch the login form initially checking for DialogResult == OK.

If OK, launch your main application form... else just let it drop through main() and exit.

If you have any specific questions on those basic items you can pose those and see what kind of tips you can get as kschuler suggested.

Good luck!
